AP7354-185W5-7

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The AP7354-185W5-7 is a fixed-output low dropout regulator manufactured by Diodes Incorporated, delivering a precise 1.85V output with a maximum guaranteed load current of 150mA. It operates within an input voltage range of 2.0V to 5.5V and maintains a tight output voltage accuracy of ±1%. The device features an ultra-low quiescent current of 0.25µA and a typical standby current of 0.02µA when the enable pin is deactivated. Packaged in a compact SOT-25-5 surface-mount format, it includes integrated current limiting and thermal shutdown protection for reliable operation across temperatures from -40°C to +85°C.

Ensure ordering quantities align with standard tape and reel packaging specifications provided by the manufacturer.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component for designs prioritizing low static power consumption and high voltage precision. The SOT-25 package offers a balance between thermal performance and board space efficiency. Consider the enable pin functionality if system-level power sequencing or deep sleep modes are required for the application.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This device belongs to the AP7354 series of ultra-low quiescent current LDOs. It shares core electrical characteristics with other variants in the family but differs in output voltage settings and physical packaging options such as SOT23 and X2-DFN1010-4. The W5 suffix specifically denotes the SOT-25 package variant without built-in output discharge.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

AP7354D-185W5-7 provides identical electrical performance but includes an active output discharge feature for faster shutdown times.
